Hcg level a 4

Jolie 🇫🇷

Do you ladies see a line? I came Bk from the hospital uti symptoms and endo pain, but i also told them i had a faint positive test. So they gave me bloodwork and my hcg level was a 4 and they said I’m not pregnant. I almost cried right there. Me and my husband haven’t said a word to each other since the doctor at the hospital broke the news. I feel like a let down. But i got 3 font positivé tests why is this happening? Anyone with positive feedback?
